/* Editor integration contract:
   Tabs: update hidden, aria-selected and roving tabindex; Arrow/Home/End keys.
   Advanced: update hidden + aria-expanded. Selection: enable applicable inputs.
   Fields: .field-group > label.field-label + input/textarea.field-input;
   .field-help / .field-error with aria-describedby, aria-invalid when needed.
   Photos: .photo-thumbnail aliases the slot image; .photo-slot containing img + .photo-slot-body + named button(s).
   Layers: button.layer-item [aria-pressed] with .layer-name, .layer-type.
   Palettes: named button.palette-button with .palette-swatch children;
   badges: button.badge-button. Do not rely on color alone for selection.
   Canvas: stage has stable positive width/height; main owns actual zoom/fit.
   Read stage.clientWidth/clientHeight minus computed padding. Set wrapper
   width/height and Fabric CSS/backstore dimensions together on format/zoom.
   Refit after revealing editor-view (rAF), ResizeObserver, and viewport resize.
   No CSS transform or forced Fabric canvas dimensions compete with controller.
   Export: app populates summary/issues, controls confirmations and disabled
   actions; expose unavailable native sharing/clipboard via hidden controls.
   Status containers are initially empty so UI never claims an unsaved success. */
